DMAMUX_CHCFG Source for SPI0 transmit/receive

Dear community,

 

I am trying to establish a slave SPI0 interface with DMA0 with DMAMUX2. When I write the DMAMUX_CHCFG_SOURCE(13) to the DMAMUX0_CHCFG2 I get all

 

DOE,

DAE,

SOE,

SAE

 

error bits of DMA0 Error status registere are set.

DMAMUX0_CHCFG2 = DMAMUX_CHCFG_SOURCE(13) |  DMAMUX_CHCFG_ENBL_MASK;

 

I am using the number 13 because of table 8-2 of ref. manual.

 

How can I tell the DMAMUX unit that I will connect it SPI0 transmit/receive?

 

 

Thanks and best regards
